Note:Wireless radio cards are ESD sensitive, especially the RF switch and the power amplifier. To avoid damage by electrostatic discharge, the following installation procedure is recommended:

Touch your hands and the bag containing the radio card to a ground point on the router board (for example one of the mounting holes). This will equalize the potential of radio card and router board. Install the radio card in the miniPCI socket. Install the pigtail cable in the cutout of the enclosure. This will ground the pigtail to the enclosure. Touch the I-PEX connector of the pigtail to the mounting hole (discharge), then plug onto the radio card. Use external lightning protection for outdoor applications.
